Fascinating! I really like the incorporation of the puzzle-solving compulsion. Hopefully, there will be a history regarding how this SCP was found. Though she comes across like a combination of a vampire and a werewolf, they're put together in such a way that it doesn't come across as being cliche. Quick question, though: Are the mirrors silver-backed or are they simply highly polished steel?

The Feral also includes elements of the wendigo, a dash of zombism, as well as the idea of a feral child. It was very much a stew of ideas. Glad it didn't come across as cliched! I was worried the blantant reference to the Feral's preference for blood while calm would be a little ham-handed.

Good question! I think I'm going to say that, before the current containment procedures were set up, testing with the SCP showed that, while silver-backed mirrors were more effective in inhibiting spectral travel, manifestations of the Wretch as well as the second state of the Child would induce shattering in the mirrors. The current containment procedures suggesting using polished steel (or they will in a second).

Indeed, a certain degree of expectation dictates the forms that 578 takes. However, in the case of the Wretch, it was much the opposite then L4D's Witch. The Witch's transformation robbed her of the cognizance or care of dignity, but the Wretch used the shift to reclaim some of hers.

123 is the Contained Miniature Black Hole, Karrin. And I think this might have been written before those games came out…? If I could actually remember what the name of them were I could check. I trust Snorlison didn't rip anything off, though.

Considering how much the rating of 578 has fallen from the old days, I guess it's time for that overdue rewrite. This is actually my favorite of the SCPs I've made, I'd hate to see it go. So I want to try to tame the text.

This is a really long. I've been away for awhile, so I've forgotten some of the quirks of posting, and probably some of the etiquette has moved past what I remember.
Hopefully this wall of text doesn't rub too many the wrong way.

I've noticed that, with this particular SCP, I've had a lot of difficulty communicating my theme.

What is 578? They're ghosts. And the Foundation has become the latest in a long line of their jailers, keeping these women constrained by cages of mirrors and wires, by prisons of puzzles and electricity.

1) SCP Researchers have their own innate biases. They perceive the world in a certain way, and they conceptualize the preternatural objects they study through that filter — "Containment". So the researchers ignore the significance of details hinting that 578 is sentient.

2) To me, SCP researchers are, at least in part, people fascinated by puzzles. They're researchers. They ask questions, and though the way to understanding may be difficult, they expect some kind of an answer exists. The person assigned to write up this document was no different. He is entranced by what all these disparite details of 578 mean. He thinks the explanation is just beyond him, that he hasn't been clever enough yet. So he writes more and more detail. The truth is, the researcher hasn't asked and probably won't ask the right question.

3) The Shattered Girl feels the world and their emotions, but each of her personas have their perceptions and psychologies warped in a way that fundamentally mocks them. For example:

The Wretch, unlike the others, is aware of her predicament. She wants to escape, but the closer she gets to freeing herself from the Foundation, the more they tighten their grip. She can't give up, and continuing on will just motivate her jailers to be more clever at punishing and confounding her and the other personas.

The Feral hungers, and will do anything to eat. Her punishment is that she will lose herself once she eats and become monstrous. Suffer eternal hunger, or suffer becoming a monster.

We've imagined scenarios where the Foundation falls. But imagine that the Foundation never falls. That it continues in some form, quietly containing and documenting. They're hoarders. And they've done their best to ensure there will always be someone to contain their hoard. 578 is never getting out. Whether they realize or not, they've become the executors of the cruel and eternal punishment these women were sentenced to.

Your post was very informative and much more compelling than your article was- which is a bad thing.

Great walls of text tend to be a deterrent on the internet, and your article is very very lengthy. Perhaps some supplementary pages could allow you to delve into more details- I look forward to your rewrite.
